Agribusiness giant ADM said on Tuesday it would reduce its carbon footprint by building a 350-mile pipeline to transport carbon dioxide for injection in central Illinois from its ethanol plants in eastern Iowa.
Carbon capture and sequestration is a relatively new concept that involves injecting the greenhouse gas in subsurface rock formations.
There are 43 ethanol plants in Iowa with an annual capacity of 4.6 billion gallons a year out of 209 plants nationwide with a capacity of 17.4 billion gallons a year.
Companies are eligible for tax credits from $12-$50 per tonne of carbon that is captured and sequestered, depending on the type of the project.
